Abstract
Radio frequency (RF) polarizer feeds and associated waveguide structures having twist features are discussed herein. In one example, a first waveguide segment spans a longitudinal axis between a feed port and a twist port and includes two stacked rounded rectangular elements skewed in minor axis alignment with respect to each other and having major axes perpendicular to the longitudinal axis. A second waveguide segment spans the longitudinal axis between the twist port and a polarizer port and is coupled to the first waveguide segment at the twist port. The second waveguide segment includes first ridge elements that span longitudinally from the twist port on first opposing walls of the second waveguide segment, and second ridge elements that span longitudinally from the twist port on second opposing walls of the second waveguide segment.
